Description Stefano Brivio 2023-03-09 11:27:32 UTC

The SELinux policy interfaces in the current passt-selinux package for RHEL 9.2 only allow libvirt to run a guest domain as unprivileged user, and to map ports in "http_port_t".

However, libvirt guests can be started as root, and the guest configuration can very reasonably include arbitrary port mappings.

We need these changes from upstream:

  https://passt.top/passt/commit/?id=41bc669866b9e408d8d4966ee06e01784949b98d
  contrib/selinux: Let passt write to stdout and stderr when it starts

  https://passt.top/passt/commit/?id=de9b0cb5fee2ea00ed7e7877ef9be8c446bca134
  contrib/selinux: Allow binding and connecting to all UDP and TCP ports

  https://passt.top/passt/commit/?id=d361fe6e809bdf3539d764cfa5058f46ce51bcbf
  contrib/selinux: Let interface users set paths for log, PID, socket files

to have proper libvirt support with SELinux on RHEL 9.2.

See also bz2172268 for the matching policy update on libvirt's side, which I'm also going to update in a bit.
